Experimental Investigation of Performance and Emission of Microalgae Chlorella Vulgaris in Variable Compression Ratio Engine

This study aims to conduct an experimental examination concerning the performance and emission characteristics of the microalgae Chlorella vulgaris when utilized in an internal combustion engine featuring a variable compression ratio. This investigation seeks to explore the effects of employing Chlorella vulgaris in such an engine on both the performance parameters, such as power output and fuel consumption, as well as the emission characteristics, including the levels of nitrogen oxides, carbon monoxide and unburnt hydrocarbons in the exhaust gases. By performing this experimental investigation, it is to contribute to the existing body of knowledge in the field of alternative fuels and renewable energy sources, specifically in terms of the utilization of microalgae as a potential substitute for conventional fossil fuels in internal combustion engines.
